Title: Seatpost shim for thudbuster
Post by: sg37409 on August 14, 2016, 07:16:06 AM

Hi - On my thorn discovery twin, I would like to fit the 27.2 thudbuster seatpost, but I need to shim it down.
Does anyone know the internal diameter of the (rear) seat tube on a thorn discovery twin ?
thanks
SG

The first batch were 29.6mm the 2nd 28.6mm, if you send me the frame number I could tell you 100%.
